Parker Series F12 Bent Axis Piston Motor

Parker F12 Series Bent Axis Piston Motors

Parker’s F12 series bent axis piston motors deliver exceptional power, efficiency, and reliability for demanding mobile and industrial hydraulic applications. Built on Parker’s proven bent axis design with a unique spherical piston concept, these motors provide superior thermal shock resistance and smooth performance under extreme operating conditions.

Designed for both open- and closed-loop systems, Parker’s bent axis piston motors operate at pressures up to 500 bar (7,250 psi) and speeds up to 7,300 rpm. The combination of gear synchronization and double tapered roller bearings ensures maximum durability and uptime, even in the harshest environments.

Available in displacements from 30 cc to 250 cc, Parker’s bent axis motors are compact, highly efficient, and thoroughly tested to deliver long service life and optimal performance. Backed by decades of engineering excellence and continuous product development, Parker motors set the standard for hydraulic power and reliability.
